BOX-TOE-FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,025, dated August9, 1887.

Application filed December 17, 1886. Serial No. 221,835. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH F. Source, a citizen of the United States,and a resident of Brockton, in the county of Plymouth and State ofMassachusetts, have invented certain new and useful Improvements inBoX-Toe-Forming Machines, of which the following, taken'in connectionwith the accompanying drawings is a specification. I

This invention relates to improvements in machines for making box-toesfor boots and shoes, and it is carried out as follows, reference beinghad to the accompanying drawings, wherein--- Figure 1 represents a planview of the machine. Fig. 2 represents a vertical section on the line AB, shown in Fig. 1. Fig. 3 repre sents a crosssection on the line 0 D,shown in Fig. 1; and Fig. 4 represents a cross-section on the line E F,also shown in Fig. 1.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

a is the frame of the machine, in bearings in which is located thedriving-shaft b, to which a rotary motion is imparted by means ofbeltpower applied to thepulley c,secured to shaft-b.

b is a pinion secured to the shaft 1) and gearing in the'teeth of. thegear (1, secured to the cam-shaft d, that is located in suitablebearings in the frame a, as shown in Fig. 2. To the shaft d is securedthe double-faced cam 6, having cam-grooves e and e on its two oppositefaces, as shown in Fig. 2.

The cam-groove e and its connecting mechanism to the male die serves tomove thelatter to and from the stationary female die, and the cam-groovee and its connecting mechanism to said male die serves to move thelatter up and down to and from the yielding follower.

The mechanism for imparting a horizontal forward-and-back motion to themale die is carried out as follows: WVithin the cam-groove e is locatedthe roll f upon the pinf, which latter is secured to the block f that isguided in stationary ways secured to frame a. The upper end of the blockf is hinged or pivoted to the lever g, which is hung at g in its rearend to frame a, as shown in Fig. 2. Between the ends of the lever g, Imake through the latter aseries of perforations, g g g, to either the isobtained.

one of which (according to the desired motion to be given to the maledie) is hinged the lower end of the link It, the upper end of which ishinged or pivoted to the inner ends of the knuckle-joint levers i and k.The rear end of the lever t is hinged to the horizontally-adjustableblock '6', which latter is made adj ustable in guides in the frame a bymeans of the screw 2', that is screwed through the frame a and looselyconnected in a suitable manner to the rear end of the block 43, as shownin Fig. 2, and by this arrangement an additional adjustment of theforward motion of the male 2' is a set-nut on the screw t', as shown inFigs. 1 and 2, for the purpose of firmly securing the screw 6 to frame aafter the position of the block t" has been adjusted.

To the forward end of the lever 75 is hinged the block Z, that ishorizontally movable in guides in the frame a.

The horizontally-mov-.

able block Z has a vertical perforation, in which the male-die rod m ismovableup and down, to the upper end of which is secured, by means of anut,m, the male die m, as shown in Figs. 1, 2, and 3. The lower end ofthe maledie rod in is hinged to the block 0, that is guided in waysattached or secured to frame a, and is provided in its lower end with apin, 0, having roll 0 located in the cam-groove e on the cam c, as shownin Fig. 2.

To the upper front end of the frame a is secured the stationary femaledie 19, having on its rear side a semicircular recess, 19, correspondingin shape to the semicircular front end of the male die m, and to the topof the said female die 1) are secured the adj ustable gages 12" 2", asusual, by means of set-screws 19 19 or equivalent devices.

Below the male die m within the recess 12 in thefemale die is locatedthe follower-die q, the upper surface of which is made to correspondwith the under surface of the male die m", as is usual in machines ofthis kind. The follower-die q is secured to the follower q, that isvertically movable in the block r against theinfluence of the coiledspring r, located around the said follower q between the top of theblock r and a collar or projection near the 7 ICO by means of thethumb-nut q, arranged on the lower screw-threaded end of the saidfollower q, as shown in Fig. 2.

The block r has on its rear side a perforation, r, in which is looselyinserted the supporting-plate .9, having trnnnions s s in its endslocated in bearings s s, secured to frame a, as shown in Figs. 2 and 4-,to enable the follower and its die to rock forward and back; and for thepurpose of causing the forward end of the follower-die to bear againstthe bottom of the recess 1) in the female die 1) during its up-and-downmotion, I secure to the plate 8 a pair of springs, s s", the lower endsof which are located inslits in the stationary projections s s 011 theframe a, as shown in Figs. 2 and I. The upper portion, 1-, of the blockr, where it surrounds the plate 8, is supported and made to rocksidewise in a recess, 8, in the upper central part of plate 8, as shownin Fig. 4;, to allow the followerdie to automatically adjust itself tothe male and female dies during its downward motion.

In connection with the machine I use an automatic picker to throw offthe box-toes as they are finished, and it is carried out as follows: Tothe upper end of the male-die rod in is secured one end of aspring-wire, t, or suitable spring projecting to one side of themachine, and having its free end located below and resting against theunder side of the male die, and to such free end is connected the linkor wire t, the rear end of which is connected to a beltcrank lever, t,pivoted at t" to frame a, as shown in Fig. 2. The other end of thebell-crank lever t" is provided with a link or wire, 11, the lower endof which is connected to a lever, t pivoted to frame (I, as shown inFig. 3, the free end of which normally rests against the periphery ofthe cam-wheel 0 while the boxtoe is being formed, and as soon as abox-toe is finished it is thrown out and off from the male die by thepicker 1, which is at this moment liberated by the free end of the leveri dropping into a cavity or recess, 0, on the periphery of the cam-wheele, as shown in Fig. 3.

a is a hood and receiving-tube, into which the finished boxtoes aredelivered by the picker device.

The operation of the machine is as follows: The shaft b is set in rotarymotion by beltpower applied to its pulley c, as hereinbefore set forth,and the female die 1) is heated by means of lamp or other suitableheating device placed below it, as is usual in machines 'f this kind.The previous]y-cutout blanks nade from leather-board or other suitablematerial) are then taken one by one and placed in proper position on thetop of the female die 19 between the gages p and held in such positionby the operator until the blank is nipped and molded between the femaleand male dies, which is accomplished by the downward and forwardmovement of the male die. After the blank has thus been shaped the maledie recedes and ascends, causing the now-finished box-toe to beautomatically delivered into the hood to by the agency of the automaticspring-picker f, as hereinbefore set forth. Another blank is then placedon top ofthe female die, and so on.

Having thus fully described the natn re, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim- 1. In abox-toe machine having stationary female die and vertically andhorizontally movable male die m, the automatic springpicker 1., attachedto spindle m or any of its parts,and having means, as described, bywhich it is released to automatically throw off and eject the box-toewhen finished, as herein set forth.

2. In combination with the stationary female die and movable male die m,the antomatic picker device, as described, consisting of the rotarywheel 0, having notch or recess a, the pivoted lever l link t, lever t,link if, and spring t, secured in one end to the maledie spindle m orany of its attachments, asand for the purpose set forth.

3. In abox-toe machine, theherein-described mechanism for moving themale die to and from the female die, consisting of the camwheel 0, pinor roll ff, block f, lever g, link h, and knuckle-levers i 7;, connectedtolink h, as and for the purpose set forth.

4-. In combination with the stationary female die and vertically andhorizontally movable lnaledie m, the follower q q, adapted to yield inthe block 1' against thcinflucuee of spring 1', the block 1' beingsupported and adapted to rock on the pivoted plate .9, said plate havingsprings s" a resting against projections s" s on the frame for thepurpose of automatically adjusting the said follower relative to themale and female dies, as set forth.

In testi mony whereofI have signed my name to this specification, in thepresence oftwo subscribing witnesses, on this 8th day of November, A. D.1886.
